To all w]: am it may concern Be it known that 1, CHARLES FISHER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Savings-Banks, of which the following is a specification.

This invention relates particularly to a slot-guard and locking device for savings banks; and the primary object is to provide an exceedingly simple and effective construction which can be manufactured very cheaply, the device being or improved I ticalsectional view of the casing, show ing the closure in position, the section be ing taken as indicated at line 3 of Fig. 1; Figp ls, an inner face view of the closure, showing the closure equipped with an im proved coin-slotdeviceand locking device; Fig. 5, an inner View of the outer plate of the closure, showing the slot-guards in po sition'; Fig. 6, a plan view of the closure with the outerplate thereof and the slotguards removed, thus exposing a springplate employed; Fig. 7, an inner face view of the outer plate of the closure; Fig. 8, a plan View of the .innerplate of the clo-' sure, this view showing the locking mechanism in position; Fig. 9, a broken view similarto Fig. 8, but showing a fillet-plate of the lock-case removed Fig. 10, a bottom view of said fillet-plate; Fig. 11, an enlarged transverse sectional view of the closure taken asindicated at line 11 of Fig. 4:; Fig. 12, a broken longitudinal"sectional view taken as indicated at line 12 of Fig. l; Fig.

13, a broken view showing the bit oi a key employed; arid Fig. 14, an enlarged broken sectional view taken as indicated at line 1i ceives theclosure B.

The closure B comprises an oval outer plate 2 and a slightly smaller oval inner plate 3,these plates being so shaped and combined as to form a housing for the looking mechanism and a housing for the slotguards. These plates have their marginal portions connected by rivets t. The inner plate 3 of the closure has the metal struck downwardly at one end to form a recess or chamber 3 for the locking mechanism, and has the metal struck downwardly at an intermediate portion to form a recess or chamber 3" for the slot-guards. The outer and inner plates of the closure are provided with registering slots 5 and 5*, respectively, forming a coin-admission slot extending through the closure. In the chamber 3" are mounted slot-guards, or guard-plates 6 and (l These are in the form of small flat plates ,which have adjacent edges meeting in the central plane of the coin-slot as indicated at. 7 in" Fig. 11. The plates are disposed adjacent the inner surface of the top plate 2 of the closure and have their remote edges bearing against points or projections 8 with which the plate 2 is equipped on its lower surface at some distance from the coin-slot, on opposite sides thereof. The guard-plates are held in position by a spring plate 9 which is of oval outline, and which has an enlarged opening 9 corresponding with the-coin-slot of the closure. The plate 9 is provided with spring-arms 9" which project inwardly from the margin of the opening 9, being preferably formed integrally with the plate 9. The extremities of the spring-arms 9 are equipped with hooks or flanges 9 which engage recesses 10 with which the guard-plates are equipped on their lower surfaces near their outer or remote edges. The guard-plates pivot, or fulcrum, at their outer edges on the under side of the plate 2, as indicated at the lines 11. The outer edges of the guard-plates are'beveled, as indicated at 12. The inner edges of said plates are beveled as indicated at 13,'the purpose being to insure the proper return of the guard-plates to the slot-closing position. The dotted lines in Fig. 11 indicate the position of the guard-p1ates after they have been forced downwardly by a coin 14 (as is shown in dotted lines). It will be understood thatthe spring-ar1ns I cut away to aflord an opening 1 which re- 9 normally hold the guard-plates in a position parallel with the top plate 2, but permit the guard-plates to swing freely when a coin is inserted. After partial insertion of the coin, it is gripped by the meeting edges of the slot-guards. In forming the chamber 3", the metal at the central portion is depressed just the proper distance to afford a wall 3 which affords a stop for the slot-guards when they are in the coinadmitting position.

The plate 9, as shown, has its outer margin secured between the outer margins of the plates 2 and 3. The plate 3 is of just sufficient size to fit within the oval opening 1 of the casing A, while the outer plate 2 has its margin projecting over the wall of the casing A.

The locking mechanism B comprises a key-barrel 15 disposed in the chamber 3 and journaled in the plates 2 and 3; an annular locking member, or ring, 16, having an enlarged bore 16 which freely encircles the key-barrel, the member 16 resting on the bot tom of the chamber 8; a spring 17 serving to hold the locking member 16 in theprojected position shown in Fig. 12; and a fillet-plate. 18 confined between the locking member 16 and the spring-plate 9, and having a downturned flange 18 which rests on the bottom wall of the chamber 8. The chamber 3 is provided near its rear end with vertical shoulders or walls 19 against which the ends of the leaf-spring 17 bear. The spring permits retraction of the locking member 16. The locking member may be moved, very much as an eccentric ring, is moved, by means of a key 20 which has a bit 20 which is adapted to turn in the member 16 of the locking member and effect the projection and retraction of the locking member. The chamber 3 is of suiiicient dimensions to permit the necessary lateral shifting of the locking member in the eccentric movement thereof which occurs when the vkey is inserted in the key-barrel and turned. The key will positively project the locking member as well as retract it; and the spring 17 will serve to hold the locking member yieldingly in the locking position shown in Fig. 12.

As will be understood from Fig. 11, in forming the depression or chamber 3", the metal is so struck as to form oppositely inclined walls 3 which permit the necessary movement of the slot-guards.

As shown in Figs. 8 and 14;, the inner plate 3 of the closure is provided at onev end 'ith a projection or catch 3 adapted to engage the inner margin of the opening 1 of the casing at one end of said opening.

The construction described is simple, cheap and readily assembled by means of appropriate assembling devices, and is thoroughly effective for its purpose.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is

1. In a device of the character set forth, the combination with a wall. provided with a coin-slot, of a plurality of substantially fiat guard-plates disposed adjacent the inner surface of said wall, and a sheet metal spring-plate equipped with integral springarms interlockingly engaging and normally holding said guard-plates in the slot-closing position.
